Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584602, here are decompositions:

43 + 31584559 = 31584602
61 + 31584541 = 31584602
79 + 31584523 = 31584602
103 + 31584499 = 31584602
163 + 31584439 = 31584602
229 + 31584373 = 31584602
241 + 31584361 = 31584602
409 + 31584193 = 31584602

Showing the first eight; more decompositions exist.
